I do not have a formula for this but be aware that Quick Base only has numerical accuracy up to 13 digits, so if you are looking to enter numbers which very high number of digits, there may need to be some planning involved, and it may depend on if you need to use them in numerical calculations.

For example you can have a text string with essentially unlimited number of digits and have a formula to display in Scientific Notation, but they would not be able to be used in arithmetic calculations.
